# Filling vacant shifts with push notifications
When a support worker cancels or a shift goes unassigned, you need a replacement fast. Instead of sending WhatsApp messages or calling around, you can alert available staff directly from the appointment in Comm.care — and the entire conversation stays on the participant's record.
Below you'll find the steps for both sides: what you do as a manager to fill the shift, and what your staff see when they respond.
> **Before you start:** phone alerts (push notifications) must be enabled on the Comm.care mobile app. If your team hasn't set this up yet, see [[Enabling and using mobile push notifications|Enabling and using push notifications]].

## For managers: filling a vacant shift
### Step 1 — Open the appointment
Find the shift that needs cover. You can get there from:
- **My Organisation → Calendar** — find the appointment in the organisation-wide view
- **My Circles → select the Circle → Calendar** — find it in the participant's calendar
Click on the appointment to open it.
### Step 2 — Add a comment and @mention available staff
Scroll down to the **Comments** section on the appointment. Type your message and use **@** followed by a staff member's name to tag them. You can tag as many people as you need in a single comment.
For example:
> *@Sarah @Tom — the Saturday 8am shift with James is now available. Are either of you free to cover it?*

### Step 3 — Staff receive a push notification
Each @mentioned worker receives an **instant push notification** on their phone — even if the Comm.care app is closed. The notification shows your name and a preview of your message.
### Step 4 — Review replies and assign the shift
Staff reply in the same comment thread (see below). Once someone confirms, update the appointment's attendees to assign them the shift. The full conversation — who was asked, who responded, and when — is captured on the appointment record.

## For support workers: responding to a vacant shift
### Step 1 — Receive the phone alert
You'll receive an instant phone alert (push notification) from Comm.care. It shows who sent the message and a preview of what they said.
### Step 2 — Tap the notification
Tapping the notification opens the appointment directly in the Comm.care app. You can see the shift details — time, participant, location, and the manager's comment.
### Step 3 — Reply in the comment thread
If you're available, reply in the comments and **@mention the manager** so they're notified of your response.
For example:
> *@Jo I can cover this — confirmed for 8am.*
If you're not available, a quick reply helps the manager move on to other staff:
> *@Jo Sorry, I'm not free Saturday morning.*

## Why use @mentions instead of WhatsApp or SMS?
| | WhatsApp / SMS | @Mentions in Comm.care |
|---|---|---|
| **Where the conversation lives** | Someone's personal phone | On the participant's appointment record |
| **Audit trail** | None — you'd need screenshots | Built in — who was asked, who replied, when |
| **Who sees it** | Everyone in the group chat | Only staff with access to that record |
| **Finding it later** | Scroll through chat history | Open the appointment, read the comments |
